Application ined :any s, 1915. serial No. 37,837.'

17 '0 all whom it may concern Be it known that I. FRANK H. HoUGI-r-Lann, a citizen of the United States. residing at Cincinnati, in thecounty of Hamilt0n and State of Ohio, have invented certain new anduseful Improvements in Folding Boxes, of which the following is aspecification.

This invention relates to improvements in folding boxes and moreparticularly to the type of box having` the folded corners, one objectof theI invention being the provision of a box of this character whichcan be made with the least waste of material and which when assembledin`form will be properly reinforced without liability7 to breakage as iseommonlythe case with boxes of this type.

A further object of the present invention is the provision of a box ofthis type which as it is formed or moved from its 'fiat position to atray or box forming position will cause the locking members thereof tomove toward locking position and thus make such operation a'simple andeasy one.

IVith the foregoing and other objects in .View which will be evident asthe description proceeds, the present invention resides in the featureshereinafter set forth and particularly claimed.

In the accompanyingdrawings: Figure 1 is a perspective view of. theinner corner of one form of box embodying the present invention. Fig. 2is a similar view thereof just previous to the extension of the sidewall and the locking of the corner. Fig. 3 is a similar view to Fig. 2taken from the opposite side. Fig. -1 is a plan view of one corner ofthe blank. Fig. l is a similar view of a modified form. Fig.y 5 is aperspective view of another modified form of lock corner. Fig. 6 is aplan view of the blank thereof. Fig. 7 is a perspective view ofanothermodified form of lock corner. Fig. 8 is a plan view showing oneend ofthe blank therefor. Fig. 9 is a detail view of a blank showing amodified form of incision for receiving the lock.

Referring to the drawings, the numeral 10 designates the blank which isscored at 11 and 19. to provide the end wall 13 and the side wall 14,these walls-being further scored as-at 15 and 16 to further provide thefold Ain corner ap 17. This corner flap is scored diagonally as at 17 sothat it may be caused to assume the position as shown in Figs. 1,

plemental iiap 1S to lock the corner flap relative thereto so that thebox may be collapsedv in a fiat relation or be extended to the variouspositions shown in Figs. '2 and 1, respectively.

In the modification shown 'in Fig. 4'@ the flap 17 is provided with theangular cut away portion '22, the supplemental flap 18 being cut to thecrease line 17a.

In the construction shown in Figs. 5 and 6 the same details as shown inFigs. 1 and 4 are carried out except that the end wall 13 is providedwith the fold in edge 22 which is held in place over the edge of thecorner flap 17h b v means of the staple 21. By this means thereinforcement is provided the full length of the free edge of the wall13.

In the construction shown in Figs. 7 and 8 the lock 19 is cut with theleast .vaste of material to provide a relatively long staple receivingsupplemental Hap 1S', the curved `edge .of the lock being substantiallycontiguous at the greaterportion thereof with the flap 1S while aportion thereofbetween the crease and the curved edge provides .1reinforcement that is not so liable to tear at the crease line as theother form.

By forming the curved lock receiving ineision 20 as shown in Fig. 9 ithas been found that the lock is more readily guided into position whenthe end wall is moved toward the side wall and that the normal tensionof the hook lock is to permanently seat itself therein. I t alsorequires no extra time nor effort to press the locking point into or outof position.

From the foregoing ldescription itis evident that with a boxuconstructed according to and embodying the present form of folded thelockaccidentally becoming released, and in view of the fact that thestaple securing flap is rigidly heldin place no great strain is thrownupon the lock when the box is set up. Itis also apparent that with a boxconstruct- "corner and lock, that there is less liability of inventionthat there is practically no WasteV of material. I

What is Claimed 15:; l. A tray box made from a single'sheet `of materialand scored to provide side and end Walls, one of such walls beingprovided with a. diago-nally creased corner flap to provide asupplemental attaching `flap, a locking hook carried by'the other Wall,a receptacle for the locking' hook carried by the corner flap carryingWall, and means for permanently securing the supplemental flap to thehook carrying Wall.

2. A tray box made from a single sheet of material and scored to provideside and end;

walls, one of such walls being provided with a diagonallyA creasedcorner flap having a supplemental attaching flap, a locking hook carriedby the other- Wall, a receptacle for the locking hook carried by thecorner flap carried Wall, and fastening device for securing thesupplemental flap to the other Wall.

. 3. AA tray box made from a single sheet of l material'and scored toprovide side and end Walls, a corner flap formed upon one end of one ofthe walls and pro-vided With a supplemental flap, means for permanentlysecuring the supplemental flap to the other Wallv` said Acorner iiapbeing folded diago nally to permit one Wall to be `folded inwardly uponthe body otv the box and the other Wall to be simultaneously extendedoutwardlyj and cooperating locking means carried by the .corner flap andthe other wall.

4. A tray box made from a single sheet of material and scored to provideside'and end Walls, a corner flap formed upon one end of one of theWalls andtprovided WithI a supplemental Hap, means for permanentlysecuring the supplemental flap to the other Wall, said corner flap beingfolded diagonallyto permit one Wall to be folded inwardly upon the bodyof the box and the other Wall to be simultaneously extended outwardly, aloclc,

ing hook carried bythe other Wall,l and a operation with the Wallcarrying the corner flap, asupplemental flap formed upon the corner flapby the severing of the locking hook, and means for permanently attachingthe supplemental Hap to the locking hook carrying Wall. A

6. A tray box made from asingle sheet of material and scored to provideside vand end Walls, each corner of the sheet being folded diagonally`from the corner of the main portion and cut to pro-vide" a triangularap whose base is the diagonal fold, and a locking flap, Whose base isthe fold or score line ofcne of the walls, the triangular iiap beingdisposed to tit coextensively'with the Wall carrying the locking' hook,and its carrying Wall being pro-vided with a slit to receive the lockinghook when the box isl set up, and

a permanent fastener for securing the. triangular Hap tol such mentionedWall.

In testimony whereof I affix my signature.`
